Abstract
A method and system provide a magnetic recording media usable in a heat assisted magnetic recording (HAMR) disk drive. The magnetic recording media includes a magnetic recording layer, a crystalline underlayer, and a crystalline heat sink layer. The crystalline underlayer is between the crystalline heat sink layer and the magnetic recording layer. The magnetic recording layer stores magnetic data. The crystalline underlayer has a first crystal structure. The crystalline heat sink layer has a second crystal structure.
